Disk drive

Abstract

A disk device constituted that a disk attitude stabilizing mechanism to rotate a disk when a front arm or a rear arm fails to grip the disk 11 and to retry a griping operation of the disk, is included.

What is claimed is:  
     
         1 . A disk device comprising: 
 a disk holding mechanism which stores at least more than one disk;    a disk griping mechanism which grips an arbitrary disk stored in said disk holding mechanism to carry the disk to a predetermined position;    a rotating mechanism which rotates the disk when said disk griping mechanism fails to grip the disk and retries a griping operation of the disk.    
     
     
         2 . The disk device according to  claim 1  characterized by that said rotating mechanism rotates the disk in a predetermined angle.  
     
     
         3 . The disk device according to  claim 1  characterized by that said rotating mechanism continuously achieves a rotating operation until the disk griping mechanism succeed to grip the disk.  
     
     
         4 . A disk device comprising: 
 a disk holding mechanism which stores at least more than one disk; and    a disk griping mechanism which grips an arbitrary disk stored in said disk holding mechanism to carry the disk to a predetermined position, characterized by that    said disk holding mechanism shifts a disk holding position upwardly or downwardly when said disk griping mechanism fails to grip the disk and retries a griping operation of the disk.    
     
     
         5 . The disk device according to  claim 4  characterized by that said disk holding mechanism shifts the disk in a predetermined amount.  
     
     
         6 . The disk device according to  claim 4  characterized by that said disk holding mechanism continuously achieves a shifting operation until the disk griping mechanism succeed to grip the disk.
